In the construction industry, one of the most sought-after and debated materials is structural steel. We at Grupo Aço Cearense receive numerous questions daily from clients, engineers, and industry professionals on this topic.
Therefore, we decided to gather the most frequently asked questions in this article and answer them in a direct, didactic, and accessible way. Follow along and check it out!
We call it Structural steel is a material manufactured specifically for use in load-bearing elements in buildings, bridges, warehouses, and industrial facilities. It is designed to ensure integrity and strength, providing safety to the entire project.
What sets it apart from other types of steel are its regulatory criteria, chemical composition, and mechanical properties, which meet the needs of each project.
Composition, malleability, weldability, resistance, and finish quality are rigorously evaluated. Therefore, when selecting any supplier, it is important to check technical certificates, product traceability, tests, and compliance with the relevant ABNT standards, such as... NBR 8800 for metal structures.
Since each structure demands specific properties, there are various types of steel available. Each profile is developed for distinct situations, varying in terms of strength, ductility, and ease of processing. Get to know them types of steel most common:
From the arrival of the raw materials to the delivery of the final product, there are a series of carefully monitored steps. The stages include ore selection, refining, rolling, cooling, heat treatments, inspections, and mechanical testing.
Before leaving the factory, each batch undergoes chemical analysis to ensure alloy uniformity. Samples are subjected to tensile, flexural, and hardness tests. Weldability tests and visual inspection verify the absence of defects.
One of the biggest differentiators of structural steel It's in the profiles and standardized formats, which optimize assembly and multiply the creative possibilities of projects.
Its versatility allows it to be used in everything from large projects to small architectural solutions. Some of the most common applications include:
Each of these solutions is only possible thanks to the metal's ability to withstand great stress, the precision of assembly, and the speed of execution of the system.
The topic of sustainability has gained momentum in recent years, especially in the construction industry. The adoption of metal structures responds precisely to this concern.
The Aço Cearense Group invests in sustainable practices such as planting eucalyptus for own supply, reducing native deforestation.
The benefits far outweigh the initial investment, bringing gains to everyone involved in the production chain. In our experience, we highlight:
Furthermore, structural steel exhibits excellent fire performance when properly coated, contributing to building safety.
Yes. Application in structures requires adherence to strict technical standards. The main document is NBR 8800, which deals with the design and execution of steel structures for buildings.
For the manufacture of profiles, there are other references, such as standards. NBR 6355 (I and U profiles) and NBR 7007 (tubular). Furthermore:
When properly designed, protected, and installed, steel can last for generations with very little need for maintenance.
We often hear questions about corrosion, but techniques such as galvanizing, epoxy painting, and constant monitoring keep the material intact even in harsh environments.
For coastal areas or areas with direct sun exposure, special alloys or additional treatments are recommended, reducing the need for interventions over the years. The cost of maintenance It tends to be much cheaper when compared to conventional materials, since inspection is visual and quick, with only occasional replacements.
The process begins with the structural design, which defines the building's loads and the function of each component. From there, the types, dimensions of the profiles, and volumes to be acquired are determined.
The engineer calculates the stresses (tension, compression, torsion) that each metal element will withstand. CAD software or manual calculations guided by technical standards are used. The result is specified in formats, classes, and quantity in tons or linear meters.
Talking to experienced suppliers ensures better material utilization and prices more aligned with the project budget. We offer technical support for simulations and accurate budgeting to our clients.
Professionals face questions ranging from the design phase to assembly:
These are common challenges, and over the decades we have accumulated practical solutions to overcome each stage methodically and safely. If you would like to learn more about how these challenges are overcome in the daily routine of engineering, we suggest our specific article on the subject. Steel structures in civil construction and trends for 2026.
Choosing the right supplier impacts every aspect of the project, from cost to safety. Below, we list the points we always recommend evaluating:
Traceability means knowing exactly where each piece, batch, or profile of steel sold comes from and where it goes. It allows for quick action if any problems are identified and meets inspection requirements.
Our constant goal is to simplify this process for our customers. Knowing the origin of the materials helps prevent fraud and access to out-of-specification items. Always request the documentation when placing your order and keep it on file.
When technical criteria are respected and the correct standards are applied, metal structures become a benchmark. They respond better to loads, vibrations, strong winds, and even fire situations, provided they undergo appropriate treatments. Properties such as ductility, strength, and predictability of the material are key differentiators.
A well-designed metal structure is synonymous with peace of mind, both for those who build it and for those who use it. In addition to structural safety, the system facilitates inspections and any necessary maintenance. This has increasingly attracted high and medium complexity projects, both in urban and rural areas.
The procedure is meticulous. A schedule is drawn up to divide the work into stages: foundations, assembly of pillars and beams, fixing of panels or slabs, scaffolding, anti-poxide treatments, and final finishes.
Much of the structure arrives at the construction site already prefabricated, speeding up the entire process. Hooks, heavy-duty screws, welds, and spacers make up the assembly. Supervision by qualified professionals is essential to ensure alignment, plumbness, and secure fastening.
Assembly can be done using small or large cranes, depending on the size and weight of the parts. This way, we increase efficiency with fewer personnel and less risk.
Many consider structural steel to be a slightly higher initial investment solution, but the experience of the Aço Cearense Group shows that the return is quick:
In addition to the direct cost of the steel, all these gains must be considered when conducting a financial analysis of the metal system.
Although concrete remains popular, steel is primarily chosen when the goal is to:
The analysis of whether to choose steel or other materials should always take into account the end use, budget, ease of maintenance, and possibilities for future expansion.
Recent innovations allow for increasingly ambitious designs. Calculation software automates detailing and simulations. 3D printing of prototypes allows for validating solutions before execution. Anti-corrosion treatments have advanced significantly.
New types of alloys and surface treatments are expanding architectural and industrial possibilities. Furthermore, real-time sensors monitor structural performance, identifying problems quickly. Designing and building with structural steel has never been so efficient and safe.
